Product Checks - NR Electric PCS-9611 Instruction Manual

Alternatively, if a portable PC is available together with suitable setting software (such as
PCS-Explorer or PCS-9700 SAS software), the menu can be viewed one page at a time to display
a full column of data and text. This PC software also allows settings to be entered more easily,
saved to a file on disk for future reference or printed to produce a setting record. Refer to the PC
software user manual for details. If the software is being used for the first t ime, allow sufficient time
to become familiar with its operation.

12.5 Product Checks

These product checks cover all aspects of the relay which should be checked to ensure that it has
not been physically damaged prior to commissioning, is functioning correctly and all input quantity
measurements are within the stated tolerances.
If the application-specific settings have been applied to the relay prior to commissioning, it is
advisable to make a copy of the settings so as to allow them restoration later. This cou ld be done
by extracting the settings from the relay itself via printer or manually creating a setting record.
This relay is fully numerical and the hardware is continuously monitored. Commissioning tests can
be kept to a minimum and need only include hardware tests and conjunctive tests. The function
tests are carried out according to user's correlative regulations.
The following tests are necessary to ensure the normal operation of the equipment before it is first
put into service.
Hardware tests
These tests are performed for the following hardware to ensure that there is no hardware defect.
Defects of hardware circuits other than the following can be detected by self -monitoring when the
power supply is energized.

User interfaces test

Binary input circuits and output circuits test

AC input circuits test
Function tests
These tests are performed for the following functions that are fully software -based. Tests of the
protection schemes and fault locator require a dynamic test set.

Measuring elements test

Timers test

Metering and recording test

Conjunctive tests
The tests are performed after the relay is connected with the primary equipment and other
external equipment.
